I missed the announcement, it might be in my email SPAM folder.
We shipped the first barrel with a PRIME designated chamber out the door to John Fillman about 2 weeks ago. I have not heard back from him on it with actual 6Creed Prime yet.
When we did internal testing with it the performance was incredible using the 6 Creed PRIME brass and a wide range of bullets. At the time I didn't know what bullet PRIME was going to be using so we tried several options with the reamers, including the 107's.
It's not my first choice of bullet for 6's but it does shoot very well in that cartridge. I'm anxious to hear from John how the barrel shoots with turnkey ammo instead of what I loaded at home against a drawn up spec. My gut says it's going to be solid.
